I bought this for an upgrade from my Alivio one. XT, my target, was very expensive, and deore price was similar. So this was my choice. I'm using it for almost two years with no problems. I rode almost 2000 km on trails (AM trails) and they are just fine. Of course I do regular maintenance on my bike. I really liked it

Installation of this crankset dropped almost a pound compared to the entry-level item that came standard on my bike. The price could not be beat. Wish the item had come with a bottom bracket, though...

These cranks are a great deal here. I use them on two of my bikes, one is the dyna sys 10 speed setup and the other is a Mega 9 9 speed setup. Cranks work great on both bikes. I like how these cranks look too.

Strong stiff and suprisingly light,It is a lot of quality crank for a very small price. The crankset looks good and you can tell it is made well just by looking at it.only 40 grams heavier than the XT due to the steel inner chainring. Stiff and strong
